指数方程是一种超越方程,掌握简单的指数方程的解法,主要有换元法和取对数法,将指数方程转化为代数方程,利用已有的知识来解决问题,还有是利用指数函数的图像与性质来解决问题;感悟其中的等价转化、数形结合、观察论证、函数与方程等重要的数学思想,学会研究问题的方法,学会学习.一、解法分析1.解指数方程和对数方程主要是运用转化的思想将方程化归为己学过的代数方程来解,同时要注意对数方程的同解变
Exponential equation is a kind of transcendental equation, mastered the simple exponential equation solution, the main exchange method and take the logarithm method, the exponential equation into algebraic equations, the use of existing knowledge to solve the problem, there is the use of exponential function The image and nature of the problem to solve the problem; perception of which the equivalent transformation, the number of combinations, observation and demonstration, functions and equations and other important mathematical ideas, learn to study the problem of methods, learn to learn. Logarithmic equation is mainly the use of the idea of conversion will be classified as learned by the algebraic equation to solve, at the same time pay attention to the same logarithmic equation
